Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978694, here are decompositions:

5 + 978689 = 978694
11 + 978683 = 978694
47 + 978647 = 978694
83 + 978611 = 978694
173 + 978521 = 978694
281 + 978413 = 978694
347 + 978347 = 978694
461 + 978233 = 978694

Showing the first eight; more decompositions exist.
